摘要： The present disclosure relates to aqueous dispersions of silver (carboxylate-azine toner) particles wherein the azine content of the particles is from about 0.01 to 10% by weight relative to silver carboxylate. The carboxylates are typically silver salts of long chain fatty acids and the azine toners are the compounds that function as development accelerators and toning agents such as phthalazine. These silver (carboxylate-azine) particles can be used to formulate imaging forming compositions that are useful in aqueous thermographic or photothermographic imaging elements.

摘要： Silver-free, aqueous-based direct thermographic materials are designed to have image tone with near neutral density. Without the use of organic silver salts containing reducible silver ions, the image is formed using a color developing agent precursor that releases a color developing agent when heated to a temperature of at least 80° C., a combination of cyan, yellow and magenta dye-forming color couplers that provide cyan, yellow, and magenta dyes, and a substituted or unsubstituted benzoquinone as an oxidizing agent. No silver metal or silver ions are purposely added to these materials. This combination of components provides a means for controlling image tone without reliance upon conventional toning agents.

摘要： Photographically useful radiation-sensitive high chloride {100} tabular grain emulsions containing iodide are disclosed. A high proportion of the {100} tabular grains contain crystal lattice dislocations extending inwardly from their peripheral edges. The dislocations are created by introducing elemental iodine into a high chloride {100} tabular grain emulsion, reducing the iodine to iodide, displacing chloride ions at the peripheral edges of the tabular grains with iodide ions, and then continuing growth of the high chloride {100} tabular grains. The dislocations in the peripheral and, particularly, corner regions of the tabular grains increase their sensitivity.

摘要： A process is disclosed of precipitating a high chloride {100} tabular grain photographic emulsion in which iodide incorporation in previously formed grain nuclei is relied upon to create the crystal lattice defects responsible for tabular grain growth. Undesirable dilution of the emulsion is avoided by replacing soluble iodide salt solution addition with iodine solution addition, allowing the volume of the iodine solution to be limited to less than 10 percent of the emulsion volume at the conclusion of tabular grain growth.
